    摘要: An information transmission network in which a plurality of information processing stations are connected in parallel to a bus line is disclosed. Each station has a communication control means and an information processor. Each control means is capable of establishing command over the bus line to the exclusion of all other stations. While command is established, the commanding station can communicate with all other stations. After one sequence of communication, command is transferred. If the station presently in command fails, the failure to transfer command in a predetermined time will be noted and another station with highest priority will assume command. If the station to which command is transferred is not operating properly, the station presently in command will detect a failure of the former station to respond to transfer of command and will thereupon transfer command to another station.
